JULIUS SOHLUETER, BROOKLYN, NEW YORK.

TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 239,984, dated April 12, 1881,

Application filed August 5,1880. (No model.)

To all whom it may concern:

Be it known that I, J ULIUs SOHLUETER, of

Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Tobacco-Pipe, of which the following is a specification.

Figure l is a central section of my improved tobacco-pipe Fig. 2, an enlarged sectional view of the upper portion thereof; Fig. 8, a sectional view of a modification thereof.

This invention relates to an improvement on tobacco-pipes whose bowls are filled from below, and has for its object to prevent the charring of the tobacco within the pipe while the smoker is not actually using it.

To this end the invention-consists in applying to the top of the bowl a valve which is so nicely balanced, or so light, that the ascending fumes of the glowing tobacco will readily lift said valve and be able to escape.

In the accompanying drawings, the letter A- represents the mouth-piece, B the outer bowl, and O the inner bowl, of the pipe. The mouthpiece or stem joins the outer bowl, into which the inner bowl is inserted from' below, leaving a smoke cavity or chamber, a, between said two bowls, as-shown. A suitable lid, D, perforated, closes the inner bowl from below. This lid may either be removable orhinged, or otherwise applied to the pipe, and the bowls B C may eitherbemadeof two pieces, as in Fig. 1, or,

especially in clay pipes, united into one piece, as in Fig. 3. The upper portion of the inner bowl, 0, is perforated, and through the upper part of the outer bowl is also made an opening,

I), or, if desired, more than one, which opening is closed by a valve or lid, E, said valve or lid being so light as to be easily raised by the ascending fumes of the tobacco.

40 The pipe is filled from below by opening or removing the cover D. The cover is then applied to keep the tobacco in place, and the tobacco is ignited from below by drawing the light through the apertures of the cover D or before said cover is applied. While the smoke is drawn through the stem A the suction, in addition to its own weight, will keep the valve E closed and prevent the escape of the smoke otherwise than into the stem and mouth-piece; but when suction is not applied the smoke will accumulate in the bowl, and would tend to char the tobacco, as though it were in an almost airtight chamber, (like wood made into charcoal,) were it not for the valve E, which, under the pressure of the smoke, will readily be raised to allow the superfluous fumes to escape. When the excess of pressure ceases the valvesettles to its seat again. v v

The construction of the valve is not a special part of my invention. It may either be a balanced valve, such as shown in Figs. 1 and 2, or a mere plate, dropping by its own weight and confined by a suitable rim, as in Fig. 3, or of other equivalent construction.

1 claim- 1. A tobacco-pipe arranged. to be filled at the lower end, and provided with a movable balance-valve, E, at the upper end, said valve being arranged to close the aperture b and to be elevated by the accumulated smoke or gases, substantially as described.

2. In a smoking-pipecomposed of two bowls,

B and G, the combination of said bowls with a p
